Water Heater Rocket Launch! - MythBusters - S04 EP21 - Science Documentary

[@MarcosCodas]

One of my all-time favorite episodes. I remember watching it when it aired originally and it totally changed my appreciation of a pressure vessel. I now have all such appliances on the outside of my house.

[@marklangridge2734]

"...and the water heater contains NO explosives!" Is such a mythbusters thing to say.

[@Number_055]

I wonder if that's a jab at the Top Gear bathtub explosion incident

[@lord_straxus]

Grant was such a great, funny and smart person. One of my favourites on the show.

[@arjanpetersen]

He died right?

[@LarixusSnydes]

@@arjanpetersen Unfortunately, yes... He died from an intracranial aneurysm in July 2020.

[@Panzerkriegen]

Tbh, Grant was always my favorite, I never much liked Keri(apparently she got on the show by just...not going away), and Tori seems more like a Set Manager than anything else. Yet, I do love this show, they don't make TV like this anymore.

[@C.Fecteau-AU-MJ13]

RIP Grant

[@Verschlimmbesserung]

Could that jeans shrink experiment have had something to do with it?

[@julitoole]

to get mister Hyneman to flinch seems like a huge thing to me props to that tank.

[@tebogomafubelu1109]

You ever seen the cement truck?

[@MrDwarfpitcher]

That one was faked I believe. Mainly because they forgot to film the reaction from them. I also heard that the slowmo camera failed at that one which is sad

[@7thsealord888]

One of my favorite episodes. I recall weaponized water heaters subsequently became a thing in a few later episodes as well. A good one for the Build Team as well.

[@ileolai]

Adam Savage said on Tested that they kept doing it because the sound of an exploding water heater was so satisfying

[@7thsealord888]

@@ileolai I can easily believe that. A VERY unmistakable effect, I'm sure. :)

Episode uploaded 7 months ago...finally!

It’s been removed from I-Tunes in Canada, so I’m so happy to see it again!

[@Romeren]

[@MrDwarfpitcher]

That water heater explosion is always one of my favorites. The results are both funny and frightening but it does remind me of aomething I notice often: if you are going to do something yourself, do it safely

[@samio3907]

41:25 man, they should have checked his cervical arteries too. Maybe then he would have got a chance to survive this aneurysm. RIP Grant

[@nicholascrow8133]

I still love how bashful John was with his "pants on fire" joke

[@shannonkohl68]

Jamie is actually underestimating how severe the steam burns could be. If you inhale that steam, and you likely would, it would scald your lungs and you would die a very slow and painful death. These sorts of injuries used to happen from steam engine explosions. Samuel Clemens (aka Mark Twain) brother was killed in such an explosion. IIRC it took him about a week to die from it.

[@Wehra96]

super heated steam can set you on fire as well, it can reach hundreds of degrees celsius in modern steam systems.

[@SuperXzm]

Once I worked at the kitchen and definitely burned my lungs, I didn't even notice at first. Steam is not just sauna and fun.

[@ShesAaRebel]

I wish we got a wider angle on that water heater. Would have been cool to see the full separation of the shell, as well as how high it went, and it coming back down.

[@MrMarinus18]

What I find remarkable is how the water heaters are so consistent. They shoot up straight every time.

[@yessitsme6884]

We need @theslowmoguys to recreate this with today's video quality!

[@jimhjortsberg2990]

@@MrMarinus18 The bottom plate is usually welded on and the weakest part.

[@Mrcats1973]

This actually happened to a rental property that my parents owned. It completely destroyed the property and caused damage to both neighbours properties. Nobody was hurt and definitely made the nightly news.

[@TheEversearcher]

The only thing that shot higher than the water heater was Jamie's eyebrows during that final detonation.

[@petetimbrell3527]

If that heater building is built "to code", its no wonder storms do so much damage. 🤣

[@sparrowflyaway]

Only the roof was to code to test whether it would stand up to the force of a hot water heater shooting through it. The rest of the house was just there to hold the roof up and look pretty on the high speed footage. No actual house is going to be constructed like that by a professional.

[@redheadsg1]

I didn't noticed before but it seems that Kari loves to break her legs for some reason. She is always at first fine but then in next scene, broken legs xD

[@MrJimheeren]

Nah she had an accident and her knee was shattered. That’s why she had those crutches for the entire season

[@harvey854]

At 26:54, that's a very clever way to use a pair of adjustable wrenches!

Watching this episode as a kid gave me a horrible fear of water heaters that hasn’t gone away

[@dunhillsupramk3]

as it should... water heaters ain't no joke..

[@Hebdomad7]

It really makes you appreciate the power of steam and it's potential to do stuff.

I saw this episode before (ofcourse...) but I never realized that they were probably really lucky that the waterheater didn't go boom on m5

[@broncotrolly]

Tori's jeans being over 100 degrees before they started was interesting. I didn't realize clothes could be that hot just walking around in the sun

[@d4slaimless]

Too bad they didn't film the full flight of the heater. P.S. But that was a great episode, I loved it and it was nice to revisit.

[@nicholascrow8133]

They do in the later revisits

[@d4slaimless]

@@nicholascrow8133yeah, they did show most of the flight for bigger heater. But for a small one it was just the starting spot. I wish there was some camera making the shot of the area from big distance, so we could see how fast it goes up and how high. It was spectacular nonetheless. Or do you mean some other episode? I kind of recall they did something similar but with a bigger building with more sturdy roof or is it my fantasy playing up?

Denim on demin is called the Canadian Dad Tuxedo up here. Fashionable? Uh, well depends on a lot of things. Is it your dad? Not fashionable? Are you the dad? Super cool!

[@bertjesklotepino]

18:03 would you use this kind of screw driver when you can just use a normal one? I think this kind is for when in outdoors and survival mode. But to actually use it while constructing this contraption is in my opinion not the best idea.

[@1Axxonn1]

oof.. this didnt age well for Grant. considering a clot was what took him from us in the first place

[@SSG_RenAstray]

I actually burned my polyester trousers when I was knocked onto the floor in a dodgeball game. I don't have it anymore, but I can prove that it was a burn, and that I can recount that I only slid across the semi-grippy floor for less than a metre (3 feet)

[@Mojova1]

I always smiled at this. "Build to California building codes" So a house made out of plywood... Lets see that thing go through a Finnish roof.

[@HappyBeezerStudios]

they managed to bust a shed with a big tank.

[@NACLGames]

Well, the Minnesota anecdote they cited was true, I checked. The heater went through multiple floors, and the roof. Said heater was in the basement to boot, meaning it probably went through a (however thin) stone or concrete base. It also did shift the house off it's foundations. It's an unbelievable amount of take-off energy. My thoughts are no roof, Finnish or otherwise, is going to stop that, maybe unless it's got steel rebar in it. Even then, you might not want it to. Energy doesn't just go away on it's own, so if the water heater can't make it through the roof, it's either going to lift the house and probably collapse it entirely, which would be rather unfortunate for anyone inside. Or it's going to ping-pong around the house, probably at over 100m/s by most calculations. Also quite unfortunate for anyone in the house.

That Denim experiment was useless. Cotton fabric has been the goto for welders and glasblowers for a reason...

Really? I thought that was wool. Wool has always been known for it's fire retardant qualities, it's still use in fire blankets today.

[@TheElrondo]

@@MrMarinus18 Yes, for sure. Glas blowers still wear cotton clothing these days. Cotton doesn't burn well, you need a big torch or fire to really get it burning. You can try lighting a piece of Denim with a match or a lighter.

He died from a ruptured artery wall. Not a blood clot. Bloot clot blocks blood. Ruptured artery is too much blood flow to the wrong area.

[@Andy.Kobayashi]

Discovery made same mistake as BBC with Top Gear for canceling the original hosts. They don't want to pay more when the show was at it's peak. They replaced Kari, Tori & Grant with new hosts. The new version of the trio (I don't remember their names) flops and the rest are history. In conclusion, TV channels are runs by greedy pigs.

[@PrograError]

This is plain BS, and fake news, they didn't cancel the host, they even allowed them one last season to close it out. The truth is they are kind of running out of good myths, the season was getting a little stale and the ratings doesn't seem to as good. Top gear was a different game...

[@jamesbisset9891]

Notice how she was on crutches in a lot of the episode? That's because she dislocated and broke her knee and I don't think it would be a good idea for someone with a broken knee to be forcing on jeans that are to small.
